Today, we’re updating WhatsApp’s terms and privacy policy for the first time in four years, as part of our plans to test ways for people to communicate with businesses in the months ahead. The updated documents also reflect that we’ve joined Facebook and that we've recently rolled out many new features, like end-to-end encryption, WhatsApp Calling, and messaging tools like WhatsApp for web and desktop. You can read the full documents here. We’re notifying everyone on the latest supported versions of our app about these updates, and you’ll be asked to tap ‘Agree’ to accept the updated terms.

People use our app every day to keep in touch with the friends and loved ones who matter to them, and this isn't changing. But as we announced earlier this year, we want to explore ways for you to communicate with businesses that matter to you too, while still giving you an experience without third-party banner ads and spam. Whether it's hearing from your bank about a potentially fraudulent transaction, or getting notified by an airline about a delayed flight, many of us get this information elsewhere, including in text messages and phone calls. We want to test these features in the next several months, but need to update our terms and privacy policy to do so.

We're also updating these documents to make clear that we've rolled out end-to-end encryption. When you and the people you message are using the latest version of WhatsApp, your messages are encrypted by default, which means you're the only people who can read them. Even as we coordinate more with Facebook in the months ahead, your encrypted messages stay private and no one else can read them. Not WhatsApp, not Facebook, nor anyone else. We won’t post or share your WhatsApp number with others, including on Facebook, and we still won't sell, share, or give your phone number to advertisers.

But by coordinating more with Facebook, we'll be able to do things like track basic metrics about how often people use our services and better fight spam on WhatsApp. And by connecting your phone number with Facebook's systems, Facebook can offer better friend suggestions and show you more relevant ads if you have an account with them. For example, you might see an ad from a company you already work with, rather than one from someone you've never heard of. You can learn more, including how to control the use of your data, here.

Our belief in the value of private communications is unshakeable, and we remain committed to giving you the fastest, simplest, and most reliable experience on WhatsApp. As always, we look forward to your feedback and thank you for using WhatsApp.
